Software install readme says...
 

install Python, version 2.0 or later (DONE)

install wxPython (DONE)

untar (DONE)

this is the part I DON'T understand...

put a line in /etc/mailcap which is similar to the
following, only replace the path to
/usr/bin/btdownloadgui.py with the one it's actually in.

application/x-bittorrent; /usr/bin/btdownloadgui.py %s; test=test -n "$DISPLAY"

Can anyone help...

:confused:

Welcome to LQ.

Where is btdownloadgui.py on your system?

david ross; this is not relavent to this thread. but would you convey this to
the hardware moderators; when replying to post would it be of help to include basic problem solves along with howto ? ie: checking hardware connections ,cables , correct alignment of cards, correct ports, irq, I/O,s;etc.
thank you david ross!

put this line: application/x-bittorrent; /usr/bin/btdownloadgui.py %s; test=test -n "$DISPLAY"
in the file /etc/mailcap. change: /usr/bin/btdownloadgui.py of the above line to the location where it actually is, such as /home/<username>/btdownloadgui.py , or /usr/local/btdownloadgui.py, etc.
